What does RT mean on a pcb
hi i am a self taught repairer of basic electronic items and have been
doing it for about 4 years, as i buy faulty items repair them then sell them on but i have a batch of about 25 PVRs i have repaired about 20 of them but there is one part on the last 4 that i need and cant identify It is on the power supply board it is labelled RT1 and looks alot like a small capacitor it has the marking 8S100L on it it is one of the early components on the board (next after the fuse- F1)) please help as i have repured the rest of the board but am sure that i need to replace this aswell as it is showing scorch marks |

Have you measured them ? They can run quite hot btw. Graham |

They look similar to NTCs too. The MOV will be 'across the line' where an NTC will be in series. Graham |

It will be a NTC inrush current suppressor.. Since the unit is not likely to be using more than a couple of 10's of watts at most you could use one such as this http://www.ametherm.com/Data%20Sheets/SL08%2010001.pdf |

They're specced by surge capability (related to size) and hot and cold resistance. You should be able to find a suitable replacement from that. Graham |

Could you please explain what a "puck light" is? I am familiar with the standard halogen downlights operating from ac mains supply via a transformer but not knowing the specifics of your particular halogen I couldn't say whether the NTC would help. |
What does RT mean on a pcb
it is labelled RT1 and looks alot like a small capacitor
Is it a microprocessor PCB? Does it say "RTS"? "Return to sender, address unknown". But that's just a guess... -- Al, the "king" |

I would guess he means the hockey puck shaped halogen fixtures meant for mounting under kitchen cabinets. |
